Grupurile de racire lichide ale Seriilor CWFR sunt proiectate pentru a lua avantajlul “free cooling”, acesta este suprimarea directain mediul extern a sarcinii termice a camerei conditionate. Aceste sisteme sunt utilizate in camerele unde sarcina termica este mare pe tot parcursul anului, chiar si in timpul iernii.

In acest caz, temperatura exterioara este putin mai mica decat temperatura camerei controlate. Astfel, apa curenta este racitaprintr-o baterie externa, in loc de ciclul frigorific.

In acest fel este atinsa o eficienta ridicata a energiei sezoniere, redu-candu-se consumul de energie la absorbtia ventilatorului.

GRUP RACIRE LICHIDE CU CONDENSATOR RACIT CU AER SI COMPRESOARE SCROLL

The liquid chillers of the CWFR Series are designed to take advantage of the “free-cooling”, that is the direct rejection to the external environment of the thermal load of the conditioned room.These systems are used in rooms where the thermal load is high during all year, even in winter.

In this case, the external temperature is rather lower than the tempe-rature of the controlled room. Thus the supply water is cooled through an external fi nned coil, instead of the refrigerating cycle.

In this way a high seasonal energy effi ciency is achieved, reducing the energy consumptions to the fan absorption.

Controlul este un factor cheie pentru un sistem de managementla sarcini partiale. Prin intermediul optiunilor diferite de manage-ment, unitatile FR sunt capabile sa asigure adaptabilitate ridicatala diferite cerinte.Controlul este realizat prin intermediul managementului compresoare-lor si un ventil modulator 3-cai.Managementul compresorului permite optimizarea functionariilor la sarcini partiale.Ventilul modulator 3-cai realizeaza controlul temperaturii apei curente(in cazul functionarii pe timpul iernii).

MOD DE CONTROL

The control logic is a key factor for a system management at part loads. Through various management options, FR units are able to assure the highest adaptation to different requirements.

The control is performed through the management of compressors and 3-way modulating valve.The compressor management allows the optimization of their running at part loads.The 3-way modulating valve performs the control of the supply water temperature (in case of winter running).

CONTROL MODE

b) Mod de f unctionare pe perioada de tranzitie Cand temperatura aerului exterior este mai mica cu 1°C

decat cea a apei curente, ventilul 3-cai alimenteaza bateria '' free-cooling'. Intregul flux de apa este pre-racit, in timp ce compresoarele refuleaza la sarcina partiala pentru a metine conditiile set-point. Acest mod de control este deosebit de important la latitudini medii:

sistemele functioneaza in aceste conditii pentru cea mai mare parte din durata de viata.

c) Mod de f unctionare pe timpul iernii Apa curenta este racita in bateria ' free-cooling', profitand

de temperatura exterioara scazuta. Temperatura apei este contro-lata de un ventil modulator 3-cai. Astfel, consumul de energieeste redus de absorbtia ventilatorului, minimizand eficienta energetica.

b) Intermediate season mode When the external air temperature is 1°C lower than the supply

water, the 3-way valve feeds the free-cooling fi nned coil. The whole water mass fl ow is pre-cooled, while the compressors run at part load, to maintain the set-point conditions.

This control mode is particularly important at mean latitudes: systems operate under these conditions for the largest part of life time.

c) Winter mode The supply water is cooled down in the free-cooling fi nned coil,

taking advantage of the low external temperature. The water temperature is controlled by the 3-way modulating valve. Thus energy consumptions are reduced to the fan absorption, maximizing the energy effi ciency.
